retro: Adapt to API changes in retro-gtk
Stop using options-set signal, use retro_core_override_option_default()
for applying options instead.
Stop using RetroMainLoop, use new RetroCore methods instead.
Stop returning value in RetroGamepad.set_rumble_state() and add
get_supports_rumble() instead. Remove poll() and emit state-changed
signal when required.
Use file paths for state and memory instead of doing IO manually.
Stop returning value in RetroCore.shutdown signal.
